NIBE Heat Pump Monitoring using Python instead of Perl

One of the most popular topics on this Blog is using the NIBE Uplink API to retrieve operational data reported by the Internet-connected NIBE heat pumps. That API is protected by OAuth2 authentication, which is a robust solution but which is rather more complicated than other APIs which simply expect an API Key or a non-expiring Token for authentication purposes.

There’s a Technical Articles page dating from 2016 which explains how to use the Perl scripting language on Linux to call the NIBE Uplink API, navigating the multiple steps of the OAuth2 handshake – see NIBE Heat Pump Monitoring via NIBE Uplink API (Perl Version). I originally chose Perl because that’s the language I was familiar with – and there was a Perl Module which handled many of the OAuth2 complexities.

Recently I’ve been learning Python for work and that’s proven to be a bit more friendly for this sort of thing. It’s also a language that more people are familiar with – and it’s rather more commonly used on different platforms, notably Microsoft Windows.

I’ve therefore adapted the original Technical Article to use Python rather than Perl and published that as NIBE Heat Pump Monitoring via NIBE Uplink API (Python Version). The Perl version is still relevant so will remain available too (especially since it has some valuable comments and responses) but my advice is for new users to follow the Python version instead.

I’ve also included some more general updates (such as the new NIBE S-Series heat pumps using an alternative API connected to and some new screenshots. The script code is also now in a GitHub Repository rather than being embedded in the Blog page – and I intend to add some more comprehensive script examples once I migrate my other scripts from Perl to Python.

Scything the Wildflower Meadow

One of the priority jobs for my “holiday” was mowing the meadow, cutting back all this year’s growth so it can be raked up and removed, helping to reduce the soil fertility to encourage the flowers and discourage the grasses. The Austrian scythe is the perfect tool for this job – quieter and no more difficult or time consuming than using a two-stoke brushcutter. This section of the garden is about 840 square meters (60 x 14; just over 1/5 of an acre) and took about 8 hours in total, over a couple of days.

Scything is more about skill than brute strength but it’s quite a (low-impact, aerobic) workout. A lot of the skill is in sharpening the blade – especially the peening to create a hard, thin edge (which I’m getting better at – though it’s tough only getting chance to properly practice once a year).
